Gert, Weissenfels-on-thc: Saale German y 'Application March31, 1934, Serial'No'. i 'l1 8;3G6 3 In Germany Apri l j l, 1933 j x Theinvention has for an object an improvement in automatically rotatableshoe supports.

The improvement'relates according to the ina vention both to the controlmovementof the hammering tools and also to the movement of the shoe,whose seam insertion, on the shoe'bottom to be hammered must be carriedpast the tools always ata definite angle. The hammering tools whichconsist for example of a ham-' mering drum and a side hammer locatedthere under must be so guided to the shoe that in every case the sidehammer bears against the shoe before the hammering drum comesintdcontact with the edge of the shoe in order to- -,avoid injury to theshoeedge that is to beham mered; This is brought about by the featurethat the carrier of the hammering tools during its movement to and fromthe shoe controlled by a cam device is given by a second cam device asupplementary movement jsuchthatthe tooltreating the edge of the shoecomes into clined to each other, assume successively the same horizontalposition in relation to the tools.

The last support is arranged" so as' to belongitudinally movable on asliding-carriage guide and the sliding carriage guide itself is capableof being swung about a horizontal pini The longi-y tudinal movement andthe angle of inclination of the shoe bottom can be adjusted without in-'terference inter se. The last-support which dur-;

ing its rotation is moved in the longitudinal direction of the last andswung pout, canbeadjusted by adjusting devices so as to execute swingsand also longitudinal movements "ofdifi erent magnitudes. The adjustingdevices are inserted" in the gear by means of which the swinging' andthe longitudinal movements areproduced.

On this shaft9! there are freely rotatable the bevel wheels 8 and 9; which serve forthe alternatedriving of the controlling shaft. [3 and of the drivingwheels 41; 48,*5Ei, .51.. The shaft 3 and the worm- 'wheel5,theintermediate shaft 9|, and the cou pling sleeve .1 movably mounted onthis shaft revolve continually. s The machine is started bytoothed-segment leverlZ. The slide 13 controls the controlling part 11,which according to its position'couples the coupling sleeve 1 eitherwith r the bevel wheel8 or with the bevel wheel9. The 1 return off-thecontrolling part ll and consequently the pedal 1B, which can be put intothe three 'posi of the coupling sleeve 'lintothe position of rest iseifected by means of the cam disk 86,86 ,which isifastened on'the shaf-tHand co-operates with justing lever I42 on its fixing bar I42 the leverI33 is swung about its pivot bolt I39 by, meansv of the forked leverI44, the sliding piece MI, and

the guide piece I40, and in this way the sliding carriage I48 can beadjusted on the slide guiding body I21 because therlever I38is connectedwith the slide I43 by means of theintermediate member I45 and joints I45and I41. From the lever I42, there is effected consequently theadjustment of the sliding carriage I48 on the slide body I21 inaccordance with the length of theshoe, as shown in Figures 13 and 14. Inthe position of the sliding carriage and of the controlling slide I35shown in Figure 8 there is'no movement of the sliding carriage becausein this case the slot 52 extends in the same direction as the slidingsurfaces I38 of the lever I38. 1

The rotation of the rotary body 52 is brought about by the star wheels50, 5|, by which the shoe support is given a half revolution when theheel or toe portion of the shoe is swung out against the tools by thewave of the. cam disk 48. By

the controlling slide I35 there are simultaneously produced by means ofthe rod I38 the longitudinal movement of the sliding carriage I48 and bymeans of the rod I33 turning about the bolt I34 and ofthe controllinglever I30 a swinging of the sliding carriage guide I2! about the boltI26. The magnitude of the angle of the swing is adjusted by means of thehead I3If independently .of the longitudinal movement of the slidingcarriag e so that the angular position of the sliding carriage guideI2'I may be the same in the case of different longitudinal controllingeffects on the sliding carriage I48 (Figures 13 and '14). As theinclination oi the toe to the heel is of different magnitudes in thecase of different forms of shoes, it is necessary to have a difierentangle of swing of the sliding carriage guide, which maybeproe I duced bymoving the bolt I3I' in the slot I30 of the lever I30. By this movementthe position of the sliding carriage guide is altered only during thetreatment of the toe (Figure 16) but not during the treatment of theheel (Figure 15) In the case of the constructional example abovedescribed the swinging of the sliding carriage guide 527 andconsequently of the shoe 68, is distributed over the entire duration ofthe longitudinal control of the sliding carriage I48. If

, now it is desired to swing the shoe onlyv temporarily during thelongitudinal controlled movement of the shoe, for example only duringthe treatment of the toe portion, this can be brought about by arranginga special cam groove for the movement of the lever I30 after the mannerof the example shown inFigure l2. Whilst previ-' ously the longitudinalcontrolled movement and the swing of the shoe were effected by means ofthe cam groove 49' of the cam 49, in this case the swing of the shoe iseffected by means of the special cam groove 49 I53 movably mounted inthe rotary body 52 is moved by means of acam groove 49?? by means of aroller I5! on the bolt I52; In the slot I30",

of the controlling lever I30 there engages a bolt I54 of the sliding rodI53. The controllinglever I30 is mounted in the supporting block 50 soas to be rotatable about bolt I32 as in the case of Figure 8, Theadjustment of the angle of swing is effected exactly as hereinbeforedescribed.

The heel support I 49 is fixed, whilst the toe support I553 is arrangedto be movable on the sliding carriage I48 in accordance with the size ofthe shoe. 0
